About Converting Stones per Milliliter to Carats per Gallon
Stone per Milliliter and Carat per Gallon both measure density — mass per unit volume — a property used to identify materials, check manufacturing quality, and predict whether something floats or sinks. As a fixed reference point, water has a density of exactly 1000 kg/m³ (1 g/cm³, 1 g/mL) at its temperature of maximum density, which is why many density figures in science and engineering are quoted relative to water. Both are mass per volume density units.
Formula
carats per gallon = stones per milliliter × 120192373.177
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per milliliter equals 6350293.18 base units, and 1 carat per gallon equals 0.0528344104716 base units, so dividing one by the other gives the direct stone per milliliter-to-carat per gallon factor of 120192373.177.
Simple example
1 st/mL × 120192373.2 = 120,192,373.2 ct/gal
1 stone per milliliter = 120,192,373.2 carats per gallon.
Real-world example
1,000 st/mL × 120192373.2 = 120,192,373,200 ct/gal
1,000 stones per milliliter = 120,192,373,200 carats per gallon.

Frequently asked questions
How many carats per gallon are in 1 stone per milliliter?
1 stone per milliliter equals 120,192,373.2 carats per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert stone per milliliter to carat per gallon?
Multiply the stone per milliliter value by 120192373.2. The converter above does this instantly to whatever precision you set.
How do I convert carat per gallon back to stone per milliliter?
Use the reverse factor: 1 carat per gallon equals 8.319995e-9 stones per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a stone per milliliter?
Stone per Milliliter (st/mL) is a unit of density.
What is a carat per gallon?
Carat per Gallon (ct/gal) is a unit of density.
Is the stone per milliliter to carat per gallon conversion exact?
Yes. Both stone per milliliter and carat per gallon are defined by fixed standards rather than physical artifacts, so the factor of 120192373.2 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
